IMPROVEMENT THE CONSTRlIII'CfJTIlI' OF SHEET-METAL BALUSTERS.

The Schedulereferred to in these Letters Patent and making part of the same.

To all whom it may conce/m: y

. Beit know'n that I, GEORGE FISCHER, of the city,

county, and State of New York, have inventedA a new and improved Sheet-Metal Balustcr for roofs, balconies, &c.; and I do hereby declare that the following is a full, clear, and exact description thereof,`which will enable others 4skilled in the art to make-and use the same, reference being had to the accompanying drawing, forming part of this specification.

The drawing represents a side view, partly in section, of my improved baluster. f

This invention relates to a new manner of making the metallic balusters, which are used on roofs, balcony-rails, 85o., and which have heretofore been made of cast-metal, as it is' too expensive to form the separate mouldings from strips of sheet-metal, and as, furthermore, in the latter case, the joints where the ends of the several strips are soldered can not be-successfully concealed. i

The' present invention consists in forming sheetmetal balusters; by spinning the same in several parts from plates, and hy connecting the several partsiu suitable manner. be produced in absolute purity, no joints being on thesides, and no flaws, from imperfect casting, marring the beauty of the design.

A, in the drawing, represents a baluster made by my improved process.

Thereby, the finest specimens can I prefer to make it of three pieces, a, b, and c, for

To spin a baluster of one piece of sheet-metal would I be impracticable for the generality of designs, as the `,blocks could not be conveniently removed, and as thev necessary strength could not be obtained.

The several pieces are spun on a'lathe, in the same well-known manner in which other sheet-metal articles are now spun.

They are then connected in suitable manner, the best inode being to leave a fiange, d, on one piece, and fit it into the other, as shown.

, A wire or other main support may be fitted through th'e baluster, to support more rmly the cornice or rail which the balusters appear to support.

I claim as new, and desire to secure by Letters Patent- Making balusters for roofs, balconies, &c., of two or more pieces of sheet-metal, which are spun into the requisite shape, substantially'asv herein shown and described.
